Different occupational groups tend to have different personality types and general value patterns but little empirical evidence is available on work values. This study compared the work values of different groups of preservice teachers with inservice teachers on two work values scales, the Work Values Inventory (WVI) and the Values Scale (VS). Eighty-seven preservice teachers and 44 classroom teachers responded to the WVI. A second group comprised of 105 vocational-technical adult education students and 59 elementary teachers responded to the VS. There was high agreement between the preservice and inservice teachers on altruism, achievement, way of life, and economic returns. There were differences in the degree of intensity of the responses between the two groups on some of the values scales which might indicate that values become more crystallized during teaching. Differences found between the adult vocational-technical students and elementary teachers appeared to exist because of different personality types. The study indicates that the validity of the VS rests on the fact that it gives a profile similar to the WVI and also differentiates between personality types. (JD)
